Ingredients
Base
- 3 Tbsp. butter (salted)
- 1 small yellow onion (finely diced)
- 2 celery ribs (finely diced)
- 2 garlic cloves (finely minced)
Roux & Seasoning
- ¼ cup flour
- 2 Tbsp. tomato paste
- 1 ½ tsp. Old Bay seasoning
- ½ tsp. salt (plus more to taste)
Liquid Ingredients
- 4 cups fish stock (or vegetable broth)
- 2 bay leaves
- 1 cup half and half
- ½ lemon (juice only)
Seafood & Garnish
- 1 lb. lump crabmeat (divided)
- Parsley (fresh, finely chopped, for garnish)
Instructions
- Cook the butter and aromatics: In a large Dutch oven over medium heat, melt the butter. Add the finely diced onion and celery, cooking for 3-4 minutes until the onion is translucent. Stir in the minced garlic and sauté for an additional 30 seconds until fragrant.
- Make the roux: Sprinkle in the flour, then mix in the tomato paste, Old Bay seasoning, and salt. Cook this mixture while stirring occasionally for 2-3 minutes to eliminate the raw flour taste and develop flavor.
- Add broth and bay leaves: Pour in the fish stock or vegetable broth, then add the bay leaves. Increase the heat to high and bring the mixture to a boil. Once boiling, lower the heat to a simmer, cover, and cook gently for 15-20 minutes to meld the flavors.
- Puree the soup: Remove the bay leaves and stir in the half and half and fresh lemon juice. Using a handheld immersion blender, puree the soup directly in the pot until smooth and creamy. Alternatively, carefully transfer to a high-speed blender or food processor to blend and then return to the pot.
- Finish with crabmeat: Gently fold in half of the lump crabmeat to the bisque until just combined and heated through. Serve the soup immediately, topped with the remaining crabmeat and a sprinkle of fresh chopped parsley for garnish.
Notes
- Use lump crabmeat for the best texture and flavor; canned crabmeat can be a substitute but may alter the taste.
- If you prefer a thicker bisque, increase the flour slightly or simmer longer to reduce liquid.
- Adjust Old Bay seasoning and salt according to taste preference.
- For a richer bisque, substitute half and half with heavy cream.
- This bisque can be made ahead and gently reheated; add crabmeat just before serving.
